Paddle a silent lagoon under starlight to watch each stroke ignite bioluminescent plankton in Lan Ha Bay. This small-group, eco-focused night kayak pairs a sunset swim and onboard dinner with guided, low-light paddling from Cat Ba.

The sky goes black over Lan Ha; the limestone islands cut silhouettes against a sharp band of stars. Paddlers slip from a low-slung escort boat into the warm, fingered lagoons—each stroke disturbing water that can flare with living light. The launch is deliberate and silent: headlamps off, voices low, and a certified eco-guide setting expectations before the glow begins.

Choose low-moon dates
Bioluminescence is brightest on new-moon or low-moon nights; check lunar phase before booking.
Bring a dry layer
Temperatures drop after paddling—carry a lightweight insulated layer for the ride back.
Protect electronics
Use a waterproof phone case or dedicated dry bag for cameras and phones—the crew will still splash while launching/kayaking.
Follow quiet paddling rules
Keep noise and lights to a minimum to avoid disturbing plankton and local wildlife; guide instructions are mandatory.
Waterproof dry bag
Protect cameras, phones and spare clothing from spray and splashes during launch and reboarding.
Insulating layer
A light fleece or windbreaker helps after paddling when temperatures drop on the return transfer.
fall
Reusable water bottle
Hydration before and after the paddle—crew may provide bottled water, but a refillable bottle reduces waste.
summer
Headlamp with red light
Useful for moving around the boat; use red mode to avoid disturbing dark-adapted eyes and the plankton display.
